VENTILATING-SI'IIELD.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed December 1, 1913. Serial No. 803,948.

To all whom it may concern:

Be it known that I, MYRON H. O. WIL- LIAMS, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Ventilating-Shields; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide a simple, economical and effective detachable obliquely disposed ventilating shield for windows, its construction and arrangement being such that the shield is clamped between the sill and the lower sash-rail of a window to permit a free current of fresh air to pass into the apartment in an upward direction while moisture due to inclement weather is trapped by the shield and caused to flow back upon the outside of the window-sill. Thus damage to the interior furnishings of the apartment by water is eliminated, such damage being, under ordinary conditions, frequent incidental to storms when windows are inadvertently left open. Another advantage of the obliquely arranged shield is that its mouth is formed by the top edge of the shield and window sash-rail to discharge upwardly, whereby drafts are avoided, and a still further advantageous result attains due to the fact that the shield may be adjusted with relation to the sash-rail, whereby the capacity of the vent-mouth is varied.

WVith the above objects in view the invention consists in certain peculiarities of construction and combination of parts as hereinafter set forth with reference to the accompanying drawings and subsequently claimed. In the drawings Figure l represents a sectional elevation of a shield embodying the features of my invention, the same being shown in connection with a window, and Fig. 2, a side elevation of the shield with parts broken away and in section to more clearly illustrate details of construction.

Referring by characters to the drawings, A represents the sill of a window-casing B, and C is a lower sash-rail of a window which is slidable in the casing. The window, as shown, is slightly raised from the sill and fitted into the gap thus formed in an obliquely disposed plate 1 forming the body of a shield, which plate extends from the sill upwardly and inwardly in concavoconvexed form, terminating at its upper end with an outwardly curved lip 1, which lip is upon a plane slightly above the lower face of the sash-rail. The shield-plate is of'approximately the same width as the windowcasing and at its end is provided with transversely disposed arms 2 that project over the upper face of the plate and are arranged to beengagedby the lower sash-rail. The engaging faces of the arms, as shown, are approximately parallel to the face of the sill-and are provided with corrugations 3, which corrugations frictionally engage the sash-rail and serve to more rigidly hold the shield in place. The outwardly inclined bottom edge 1 of the shield-plate is merged into a rearwardly disposed foot-strip 4:, which strip in turn is connected to the shieldplate proper by two or more straps 5 constituting braces. By this construction the arms 2 arearranged to abut the partingrails of the sash-frame and thus form a comparatively tight joint therebetween. In the described form of shield it is obvious that provision is had whereby the said shield may be adjusted in or out with respect to the sash-rail of the window, whereby the vent mouth which is formed between said sash-rail and lip 1' of the shield, may be varied as, for example, the shield in this instance is shown adjusted inwardly to form a vent mouth of maximum capacity and to diminish the area of the mouth the window is slightly lifted and the shield pushed outwardly and thereafter the window is again drawn down upon the arms to lock the shield in its adjusted position, attention being called to the fact that the foot-strip 4 serves as a support for the shield to resist downward pressure of the window sashrail. By this construction it is obvious that there is no tendency of the shield being displaced by blasts of wind as the frictional contact between the arms 2 and sash-rail will be sufficient at all times to resist such wind-strains. It is obvious that, in a beating rain-storm, sheets of water having a tendency to enter the apartment will strike the face of theshield and be deflected downwardly, whereby the water is drained off in an outward direction from the sill. The outwardly turned lip 1' will also serve to trap any spray or dust which may tend to travel upward; Thus air is admitted freely in an upwardly direction to vent the room or apartment, While moisture or dust is effectually trapped, and the frequent damage to draperies and other articles of furniture incidental to rain-storms is avoided. Trapping of the moisture or dust is due to the fact that the overhanging top edge of the lip Will trap or collect moisture or dust as it slides upvard through the influence of the draft in contact with the curved surface of the plate, it being understood that this lip may be varied as to curvature Without departing from the spirit of my invention.

When not in use, the shield can readily be removed from its position and, While I have shown in this exemplification of my invention a shield formed from a thin metal plate, it is obvious that Wood or any other satisfactory material may be utilized to advantage in some instances. The shields may Copies also be finished to conform harmoniously with the surrounding fittings.

I claim:

A Windouattachment comprising an obliquely disposed shield having a curved lip at its upper edge constituting a trap, feet extending from .the shield adapted to rest upon the sill of a Window-casing, and transverse arms extending over the upper face of the shield arranged to be engaged by the lower sash-rail of the Window.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukee and State of Visconsin in the presence of two Witnesses.
